Interface to create or load attribute map.
When creating new attribute map returns map with predefined set of statistics.
Note that number, name and type of attributes should be in sync with resolved interface columns,
meaning that columns with attribute names should have statistics enabled, otherwise it will not
collect anything, resulting in incorrect filtering.
